Definitions

  • the present disclosure relates to transparent glass-ceramic materials which contain a spinel solid solution as the main crystalline phase, corresponding precursor alumino-silicate glasses, articles made of said transparent glass-ceramic materials as well as a method for manufacturing such articles, and structures comprising a sheet made of such glass-ceramic materials and electronic or optoelectronic devices comprising such structures.
  • the transparent spinel glass-ceramics display a high transmission in the 400-1000 nm range and are environmentally friendly (free of arsenic and antimony). They are industrially obtained in an easy way insofar as their precursor alumino-silicate glasses show suitable liquidus (low temperature of liquidus and high viscosity at this temperature).
  • Some transparent spinel glass-ceramics also display interesting strain points and coefficient of thermal expansion. They are suitable substrates for high temperature growth of high quality monocrystalline or poly crystalline silicon thin films for example. Structures including such substrates with such thin films thereon can be used in photovoltaic devices, flat panel devices and liquid crystal devices.
  • US Patent No. 4,687,750 relates to transparent glass-ceramics containing gahnite.
  • the composition of the precursor glasses contains Ti0 2 as nucleating agent. Minor amounts of Zr0 2 may be included in the composition without adversely affecting the properties of the crystallized products. Nonetheless it is explained that Zr0 2 is unnecessary as a nucleating agent as Ti0 2 is a much more efficient nucleating agent. Moreover Zr0 2 is much less soluble than Ti0 2 in the glass, hence its presence hazards unmelted particles and/or devitrification in the glass and requires higher melting temperature.
  • a fining agent such as AS2O3 and/or Sb 2 03 may be added to the batch.
  • US Patent No. 5,476,821 describes high modulus glass-ceramics containing fine grained spinel-type crystals. Nucleation efficiency is enhanced by the presence of components such as Ti0 2 , Zr0 2 and NiO, and also high levels of A1 2 0 3 .
  • US Patent No. 5,968,857 describes transparent glass-ceramics containing spinel as a predominant crystal phase.
  • the composition of the precursor glasses contains Ti0 2 and/or Zr0 2 as nucleating agents. Fining agents such as As 2 C"3 or Sb 2 C"3 may be added to said precursor glass compositions.
  • L.R. Pinckney the inventor of said US Patent No. 5,968,857, has also disclosed such transparent spinel glass-ceramics which display high strain point in the Journal of Non-Crystalline Solids, 255 (1999), pp. 171-177.
  • the described glass-ceramics are able to withstand thermal treatments at 1000°C without deformation.
  • L.R. Pinckney has observed that precursor glasses melted with Ti0 2 (but without arsenic) leads to glass-ceramics showing a gray color and so having a low transmission in all the visible range.
  • US Patent Application No. 2005/0096208 describes glass-ceramics containing spinel, sapphirine or cordierite as a main crystalline phase. Said glass- ceramics can be obtained in forming precursor glasses by the float method and then by ceramming the formed glasses.

  • P 2 O 5 , Ti0 2 , Zr0 2 , Sn0 2 and Ta 2 0 5 are proposed as nucleating agents.
  • Sn0 2 is also proposed as fining agent.

  • Ti0 2 is disclosed as a preferred nucleating agent. It may be used in a large amount.
  • the Figure shows complete transmission curves (as a function of wavelength) of comparative examples A and B and inventive examples 1 and 3.
  • the inventors have considered the technical problem of providing spinel glass-ceramics (i) free of any toxic fining agent (free of AS 2 O 3 and Sb 2 0 3 ), (ii) showing a high transmission in the visible and near IR (such a high transmission is very important in the case of photovoltaic or equivalent applications: the glass-ceramic used as superstrate so allows a maximum of solar energy to reach the silicon layer), i.e.
  • the transparent spinel glass-ceramics disclosed herein also display a high strain point (higher than 850°C, more preferably higher than 875°C and most preferably higher than 900°C), as well as a CTE in the 30-40x10 " 7 K _1 range (25-300°C).
  • a high strain point higher than 850°C, more preferably higher than 875°C and most preferably higher than 900°C
  • CTE in the 30-40x10 " 7 K _1 range 25-300°C.
  • Said advantageous characteristics are particularly advantageous if the glass-ceramics are aimed to be used as substrates for layer(s) made of a semi-conductor, especially for crystalline silicon layer(s). Therefore, their CTE provides a relatively close thermal match to silicon, and their high strain point allows to be used them as a substrate to make high quality crystalline silicon by growth at high temperature (> 850°C).
  • glass-ceramics disclosed herein have more particularly been developed in reference to the five above stipulations (so as to be particularly suitable as substrate for layer(s) made of a semi-conductor, especially for crystalline silicon layer(s)) but that the disclosure also encompasses glass-ceramics complying with only the first three stipulations and usable in others contexts. Such transparent spinel glass-ceramics are easily obtained, free of toxic fining agent and are per se interesting.

  • the composition of said material (expressed in percentages in weight) is free of As 2 0 3 and Sb 2 0 3 , with the exception of unavoidable trace thereof, and comprises Sn0 2 , Ti0 2 and Zr0 2 , and less than 100 ppm of Fe 2 0 3 .
  • a transparent material here means a material showing a transmission of at least 50% for any wavelength in the 400-450 nm range (preferably higher than 70% for any wavelength in the 400-450 nm range), higher than 80% for any wavelength in the 450-520 nm range and higher than 85% for any wavelength in the 520-1000 nm range, such a transmission being measured through a thickness of 1 mm of material.
  • the main crystalline phase observed in the material is a spinel solid solution of formula (Zn,Mg)Al 2 0 4 (being it not impossible that other elements like titanium or iron enter in the solid solution). It represents at least 75% (in weight %) of the crystalline matter.

The fining efficiency and the absorption both increase with the tin oxide level.
  • Ti0 2 is advantageously present (very advantageously present) within the indicated ranges. It has to be efficient enough as nucleating agent (otherwise the material is not transparent) and not responsible of a strong absorption.

  • the disclosed glasses display liquidus temperature lower than 1500°C and a viscosity at the liquidus higher than 700 dPa.s
  • Iron is an impurity which may be introduced by the raw materials. Iron can be present at a concentration of less than 100 ppm to limit absorption. Its level is advantageously less than 80 ppm, very advantageously it is less than 60 ppm.
  • the glass-ceramic materials have a composition, expressed in percentage by weight of oxide, which essentially consists of:
  • the composition "essentially consists of the given list of compounds (oxides). This means that in the glass-ceramic materials according, the sum of the listed compounds (oxides) represents at least 95 weight %, generally at least 98 weight %. It cannot be excluded that other compounds may be found in low quantities in said glass-ceramic materials (obviously any other compounds that have not a strong detrimental action on the required properties, more particularly on transparency). So the presence of Ce0 2 is (quasi) excluded (the composition of the glass-ceramics generally includes no Ce0 2 ), also the significant presence of B 2 0 3 (the composition of the glass-ceramics generally includes no B 2 0 3 ).
  • the composition advantageously comprise more than 55 % by weight of Si0 2 and within said composition, the molar ratio (R 2 0 + R0)/A1 2 03 is between 0.5 to 1.5, R 2 0 being the sum of the moles of alkali oxides and RO the sum of the moles of alkaline earth oxides plus ZnO.

  • A1 2 0 3 is one of the main component of the crystals. It can be present at a minimum amount to ensure sufficient crystallization and not at a too high amount to then produce an unacceptable devitrification of mullite, hence the above indicated preferred range.
  • ZnO and MgO are also constituents of the crystals. Therefore a minimum amount can be incorporated. At a too high level, MgO is detrimental for transparency. The above indicated preferred values take that into account.
  • BaO stays in the residual glass. It has been observed that it helps in having a good transparency but its amount has to be limited to keep enough crystallinity and a high strain point, hence the above indicated preferred range.

  • Another means of achieving a high quality polycrystalline silicon layer is to perform a high temperature rapid thermal annealing step of a previously grown polycrystalline silicon layer (B. Rau et al, Materials Science and Engineering B 159-160 (2009) 329-332).
  • Photovoltaic cells usually include at least one transparent conductive layer located between the superstrate and the at least one semiconductor absorber layer.

  • the transparent conductive layer usually has significant absorption below a wavelength of 400 nm, which does not result in the generation of collectable charge carriers. Therefore a superstrate should preferably have a high transmission for wavelengths above 400 nm.
  • this semi-transparent conductive layer usually has significant absorption up to a wavelength of about 450 nm.
